Daily Beast gains on Reddit and Facebook as Google traffic falls
Reddit and Facebook have made up for falling referral traffic from Google for the Daily Beast, Cannes Lions event hears.

Apache Flink is uniquely positioned to serve as the backbone for AI agents, equipping them with the powerful new tool of stream processing. Join Steffen Hoellinger at this year's Berlin Buzzwords to explore how Flink jobs can be transformed into “Agents”—autonomous, goal-driven entities that dynamically interact with data streams, trigger actions, and adapt their behaviour based on real-time insights.

Pandemic-era slump in ivory and pangolin scale trafficking persists, report finds
A recent report surveying seizures of pangolin scales and elephant ivory over the past decade has found a sharp decline following the COVID-19 pandemic. Using data from media reports, public documents, and criminal intelligence and investigations, analysts at the Wildlife Justice Commission (WJC) found authorities seized more than 370 metric tons of pangolin scales and […]

Model Predictive Path-Following Control for a Quadrotor
Automating drone-assisted processes is a complex task. Many solutions rely on trajectory generation and tracking, whereas in contrast, path-following control is a particularly promising approach, offering an intuitive and natural approach to automate tasks for drones and other vehicles. While different solutions to the path-following problem have been proposed, most of them lack the capability to explicitly handle state and input constraints, are formulated in a conservative two-stage approach,…

Iran asks its people to delete WhatsApp from their devices
Iranian state television on Tuesday afternoon urged the country’s public to remove the messaging app WhatsApp from their smart phones, alleging without offering any evidence the app gathered user information to send to Israel. WhatsApp is end-to-end encrypted, which means a service provider in the middle can't read messages. WhatsApp says it does not track users' precise location and does not track personal messages. Iran had banned WhatsApp in 2022 following mass protests. It lifted the ban …

Breaking the Trend: How to Avoid Cherry-Picked Signals
Our empirical results, illustrated in Fig.5, show an impressive fit with the pretty complex theoritical Sharpe formula of a Trend following strategy depending on the parameter of the signal, which was derived by Grebenkov and Serror (2014). That empirical fit convinces us that a mean-reversion process with only one time scale is enough to model, in a pretty precise way, the reality of the trend-following mechanism at the average scale of CTAs and as a consequence, using only one simple EMA, app…

Evaluation of Modular Polynomials from Supersingular Elliptic Curves
We present several new algorithms to evaluate modular polynomials of level $\ell$ modulo a prime $p$ on an input $j$. More precisely, we introduce two new generic algorithms, sharing the following similarities: they are based on a CRT approach; they make use of supersingular curves and the Deuring correspondence; and, their memory requirements are optimal. The first algorithm combines the ideas behind a hybrid algorithm of Sutherland in 2013 with a recent algorithm to compute modular polyno…

Nippon Steel’s $14.9bn acquisition of US Steel closed on Wednesday,
confirming an unusual degree of power for the Trump administration after the Japanese company’s 18-month struggle to close the purchase.
Under the deal terms, Nippon bought 100% of US Steel shares at $55 a share, as it first laid out in its December 2023 offer for the well-known and struggling steelmaker.
A press release on the filing also discloses details of a national security agreement inked with the Tr…
